Quercus robur 'CONCORDIA'

Oaks are common trees of our natural woodlands. They border our ponds, occur naturally in our mixed forests, and make magnificent specimen trees in our parks and arboretums where less common species or rare varieties can be seen.

Concordia is an English oak variety raised in Belgian nursery Van Geert in 1843. It is truly a sensation among oaks as it has very attractive foliage of golden yellow colour in spring and yellow to fresh yellow-green in summer. The leaves are shallowly lobed and appear clustered along the branch tips. The tree often makes another portion of new foliage at the end of summer. The leaves, though being bright yellow are not prone to sunscorch as some other trees and shrubs with yellow foliage. Quite the contrary – this oak must be grown in full sun.

Concordia grows slowly to moderately about 10m tall when 20-25 years old. It makes a narrowly pyramidal crown when young changing to widely rounded with age. It can take any type of pruning to achieve a desired shape or to control its size.

Oaks are not fussy about soil type, they can take anything from slightly alkaline to slightly acidic conditions. They do well in well-drained soil, moist is good but boggy is fatal. Once established they withstand drought and city pollution. Newly planted trees need to be staked for 2-3 years to establish. Fully hardy to -34°C (USDA zone 4).
